DRAG-SAW.

SPECIFICATION forming part of Letters Patent No. 374,994, dated December20, 1887.

Application filed July 19, 1887.

To all whom it may concern.-

Beitknown that I, FRED. N. PEPPERLING, a citizen of the United States,residing at Stuart, in the county of Holt and State of Nebraska, haveinvented a new and useful Improvement in Drag-Saws, of which thefollowiug is a specification.

' My invention relates to improvements in fire-wood dragsaws; and itconsists in certain novel features, hereinafter described and claimed.

In the accompanying drawings, which fully illustrate my invention,Figure l is a perspective view of my improved machine; and Figs. 2 and 3are side elevations of the same, taken from opposite sides. Fig. 4 is adetail view. Referring to the drawings by letter, A A designate twosimilar standards erected upon a common sill or base piece, B, adaptedto rest upon the ground and connected at their upper ends, as shown.

O designates a bar hinged at one end to the upper ends of the standardsand provided at its opposite end with the depending plate D, having acentral vertical slot, E, and provided with the pivoted teeth F nearitslower end on opposite sides of the said slot. The bar G is provided witha central longitudinal slot, G, for a purpose hereinafter set forth. Oneofthe standards A is provided at its upper end with an upward extension,H, and to the side ofthe said standard and the end of the eXtension'Isecure a bracket or keeper, I, having a series of notches, J, along itsrear edge. Through this keeper or bracket I pass a lever, K, one end ofwhich is pivoted to the hinged bar 0 about centrally of the same, andthe other end of which projects from the keeper and is provided with acatch which. normally engages one of the notches J. This catch comprisesa sliding plate, L, held to the under side of the lever K, the handle M,connected to the sliding plate and pivoted to the lever K, and thespring N, secured to the under side of the lever and bearing on thehandle to depress the same and throw the sliding plate into engagementwith one of the notches J. This lever K is provided with a horizontallongitudinal slot, 0, about midway its ends,and the end of a crank-arm,P, is fitted in this slot. This crank-arm 1? forms one end of arock-shaft,which is journaled on Serial N0.2-l-l,762. (N0 model.)

top of the hinged bar G near one end of the longitudinal slot Gtherein,and Q designates an arm or lever, which projects upward from theend of the rock-shaft opposite the crank-arm P. R is a cord which hasone end secured to the upper end of the arm or lever Q, and extendstherefrom over a pulley, S, journaled in the upper end of a bracket, T,secured to the lever K near the pivoted end of the same, and thence downthrough the slot G to the pitman U,to which it is secured near the endof the same. The saw V is secured to the front end of this pitman U andextends therefrom through the slot E in the plate D. The rear end ofthepitman'U is projected between the standards A A'and mounted on thecranked portion IV of the shaft X,which is journaled in the rear sidesof the standards and projects past the same, one end being provided withthe crankhandle Y and the other end having a gearwheel, Z, mountedthereon.

A is a gear-wheel j ournaled below the gearwheel Z and meshingtherewith, and B designates a fly-wheel mounted on the same shaft as thegear-wheel A and serving to give the machine a smooth and easy motion.

0 designates a longitudinallyslotted baror plate pivoted to the side ofone of the standards A and adjustably secured to the hinged bar 0 bymeans of a thumb-screw, D, as shown.

The operation of my device will be readily understood. The machine isplaced in posi tion with the saw resting on the log and passing throughthe slotted plate D. The teeth F are then forced into the log and thelogthereby held from rolling. The crank-handle Y is then turned so as toreciprocate the pitman U and thereby draw the saw back and forth acrossthe log. As the saw advances through thelog the lever K is raised, sothat the pitman will be lowered, and thus kept at all times in theproperposition to prevent buckling ofthe saw. The hinged bar 0 can bereadily adjusted by means of the slotted bar 0 and thumb-screw D todifferent heights, so that the teeth F can be readily forced into logsof various diameters.

It will be observed that my device is composed of few parts and is verysimple in construction, and it is thought that its advantages will bereadily appreciated.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,

1. The combination of thestandards,the bar 0, hinged thereto, the sawarranged below the said bar, the lever K, pivoted to the said bar andadjustably held to the standard, the rockshaft mounted on the bar 0, andthe crank-arm P and lever Q, formed on opposite ends ofsaid shaft, thecrank-arm being fitted in a longitudinal slot in the lever K and thelever Q being connected with the saw, substantially as specified.

2. The combination of the standards,the bar 0, hinged thereto, the sawarranged below said bar, the slotted lever K, pivoted to said bar andadjustably held tothe standards,the rockshaft mounted on the bar 0, thecrank-arm P and the lever Q, formed on opposite .ends of said shaft, thearm P, fitting in the slot of the lever K, the pulley S, carried by abracket, T, 20 on the lever K, and a cord, R, passing over the pulley Sand having its opposite ends secured to the lever Q and connected to thesaw, substantially as specified. I

In testimony that I claim the foregoing as 25 my own I have heretoaffixed my signature in presence of two witnesses.

FRED. N. PEPPERLING.
